As someone who just got into brewing, and is getting ready to bottle my first beer tonight, I would tell you to get one of the kits from someone like Midwest Supplies. Their basic kit will get you most of the tools and things you'll need (and would likely be least familiar with).
You can get one of those for ~$60 plus shipping (unless you have a local shop, in which case you get to save shipping, but pay a little more with taxes), I paid for the $90 kit with the auto-siphon and the glass carboy (ore shipping, but more nice things to have eventually), but this is completely up to you and your budget.
You'll also need a pot to brew in, the bigger the better, and stainless is nicer than aluminum, but get what you can afford, I bought one from Wal-mart for $50 that is just over 5 gallons, so you can boil about 3.5-4 gallons in it very well.
Other little things that were not in my kit, but I ended up buying (or wishing I did):
A Thermometer (~$10)
More sanitizer (~$10)
Cleaner (Oxi-Clean ~$7)
A plastic trash can to use for sanitizing tubing and bottles (~$5)
Last but not least, you need something to brew! I would recommend an extract kit for the ease and low initial cost, and that will set you back ~$30 depending on what you get.
If you get a kit it'll give you most of what you need, and you can add to it later with more buckets and bottles, but it's a good way to start!
Welcome to the joy of home brewing!
